Color Strength and Colorfastness of Flax Fabrics Dyed with Natural Colorants

摘要

Flax fabrics were dyed with natural colorants extracted from animal and plant sources. The colorants used were cochineal, red sandalwood, madder root, and osage orange. The influence of the order of mordanting on color strength of dyed fabrics was analyzed. Colorfastness tests for washing, crocking, and perspiration were performed. Results obtained were correlated with color strength analysis. Scientific analysis and interpretation of natural dyeing processes is essential to demonstrate the. economic feasibility of dyeing flax and other natural fibers with environmentally benign natural colorants.
